Objective:To investigate whether repeated tirofiban injections can continuously inhibit platelet aggregation in the arterial duct and affect its closure in neonatal canines.Methods:Four 24-month-old pregnant beagles underwent cesarean sections in two batches (two dogs per batch) 1-2 days before the expected delivery date at the Xuzhou Medical University Animal Experiment Center. The first litter of 21 neonates served as the control group (receiving 10 ml/kg normal saline) and were randomly divided into 1-h ( n=7, injected immediately after birth), 4-h ( n=7, injected at 0 h and 2 h after birth), and 12-h subgroups ( n=7, injected at 0 h, 2 h, 4 h, 6 h, 8 h, and 10 h after birth). The second litter of 18 neonates served as the experimental group (receiving 10 ml/kg tirofiban) with identical subgroup assignments ( n=6 per subgroup). Echocardiography was performed at 1 h, 4 h, and 12 h after birth to measure arterial duct inner diameter, maximum shunt velocity, and left atrial diameter/aortic root diameter (LA/Ao) ratio. Plasma platelet-derived growth factor (PDGF) was detected by enzyme-linked immunosorbent assay, while platelet membrane glycoprotein Ⅱb-Ⅲa in the arterial duct was assessed by Western blot and immunohistochemistry. Data were analyzed using t-tests, one-way ANOVA, Chi square tests, or Fisher's exact test. Results:No significant bleeding tendency occurred in either group. Two control neonates (one each in the 4-h and 12-h subgroups) died. In both control and experimental 1-h subgroups, all arterial ducts remained open, with no significant differences in ductal diameter, shunt velocity, or LA/Ao between groups (all P>0.05). In the 4-h subgroups, all experimental neonates had patent ducts arteriosus, while two controls exhibited closure; the experimental group had larger ductal diameters [(1.05±0.05) vs. (0.55±0.44) mm, t=－2.75, P<0.05)] and higher LA/Ao ratios (1.31±0.09 vs. 1.14±0.03, t=－4.90, P<0.05), but lower maximum shunt velocities [(107.06±17.47) vs. (153.74±12.78) cm/s, t=4.54, P=0.002). In the 12-h subgroups, all the controls had closed arterial ducts, while four of six experimental neonates exhibited closure, though the difference in closure rate was not statistically significant (6/6 vs. 4/6, Fisher's exact test, P=0.455). Plasma PDGF and glycoprotein Ⅱb-Ⅲa levels did not differ between two 1-h subgroups (all P>0.05). However, the 4-h and 12-h experimental subgroups showed lower PDGF levels [(373.5±13.1) vs. (880.3±80.2) pg/ml, t=10.81; (356.7±35.0) vs. (1 111.2±125.3) pg/ml, t=9.74; both P<0.05] and reduced glycoprotein Ⅱb-Ⅲa expression (0.32±0.07 vs. 0.80±0.23, t=3.29; 0.42±0.07 vs. 0.92±0.26, t=3.24; both P<0.05) compared to controls. Conclusion:Repeated tirofiban injections sustainably inhibit platelet aggregation in the arterial duct of neonatal canines and delay ductal closure, suggesting that intraductal platelet aggregation may be one factor influencing this process.

ObjectiveTo investigate the alleviating effect of calcium cyanamide （CaCN₂） soil fumigation on replanting problems of Rehmannia glutinosa. MethodsNewly soil （NP） was used as the control group， while three treatment groups were established： replanted soil （RP）， newly soil treated with CaCN₂ （120 g·m²， tillage depth 25 cm） （NPCC）， and replanted soil treated with CaCN₂ （RPCC）. R. glutinosa was cultivated in all groups. At harvest， the tuber agronomic traits （number of enlarged roots， maximum root diameter， fresh weight， dry weight） were measured. The content of catalpol and rehmannioside D was quantified by ultra-high-performance liquid chromatography （UPLC） to evaluate medicinal quality. Rhizosphere soil available nutrients and enzyme activities were analyzed by assay kits. The community structure and composition of fungi and bacteria in rhizosphere soil were assessed via internal transcribed spacer 2 （ITS2） sequencing and 16S rDNA sequencing， respectively. ResultsCompared with NP， the RP group showed obviously reduced in tuber agronomic traits and quality indicators （P0.05）. However， the RPCC group showed significant improvement in agronomic traits and a notable increase in rehmannioside D content compared to RP （P0.05）. The contents of available phosphorus and potassium in RPCC and NP groups were obviously lower than those in RP （P0.05）. The polyphenol oxidase soil （S-PPO） activity in RP was obviously lower than in NP （P0.05）， while sucrose soil （S-SC）， acid phosphatase soil （S-ACP）， and S-PPO activities in RPCC were obviously higher than in RP （P0.05）. Microbial richness and diversity in RP were obviously higher than in NP （P0.05）， whereas no significant differences were observed between the RPCC and NP. The relative abundances of fungal genera Nectria， Myrothecium， Tomentella， and bacterial genus Skermanella were obviousl lower in RPCC and NP than in RP （P0.05）. Correlation analysis that S-ACP activity was positively correlated with the content of rehmannioside D （P0.05）. Fungal genera Engyodontium and Alternaria， and bacterial genera Pir4 lineage， Pirellula， Methyloversatilis， Brevundimonas， Ralstonia， and Acidibacter were obviously positively correlated with tuber dry weight （P0.05）. Conversely， fungal genera Pseudaleuria， Nectria， Haematonectria， Ceratobasidium， and bacterial genera Streptomyces， Skermanella， RB41， Gemmatimonas， and Bacillus were obviously negatively correlated with dry weight （P0.05）. The fungal genus Alternaria and bacterial genera Brevundimonas， Ralstonia， Acidibacter， and Dongia showed positive correlations with medicinal quality of R.glutinosa tuber， while fungal genera Pseudaleuria， Nectria， Stachybotrys， Fusarium， Gibberella， Ceratobasidium， and bacterial genera Sphingomonas， Skermanella， RB41， Gemmatimonas， and Bacillus were obviously negatively correlated （P0.05）. ConclusionCaCN₂ soil fumigation can significantly improve enzyme activities in replanted Rehmannia rhizosphere soil， enhance the utilization of available nutrients， reshape microbial community structure of replanted R.glutinosa at the family and genus level， and notably improve tuber agronomic traits and medicinal quality. This study provides a novel approach to alleviating replanting problems and offers insights for the integrated development of standardized cultivation techniques， including soil disinfection， nutrient-targeted regulation， and microbial inoculant application.

Given the increasing concern regarding antibacterial resistance, the antimicrobial properties of naphthoquinones have recently attracted significant attention. While 1,4-naphthoquinone and its derivatives have been extensively studied, the antibacterial properties of 5,8-dihydroxy-1,4-naphthoquinone derivatives remain relatively unexplored. This study presents a comprehensive in vitro and in vivo analysis of the antibacterial activity of 35 naturally sourced and chemically synthesized derivatives of 5,8-dihydroxy-1,4-naphthoquinone. Kirby-Bauer antibiotic testing identified three compounds with activity against methicillin-resistant Staphylococcus aureus (MRSA), with one compound (PNP-02) demonstrating activity comparable to vancomycin in minimum inhibitory concentration, minimum bactericidal concentration (MBC), and time-kill assays. Microscopic and biochemical analyses revealed that PNP-02 adversely affects the cell wall and cell membrane of MRSA. Mechanistic investigations, including proteomic sequencing analyses, Western blotting, and RT-qPCR assays, indicated that PNP-02 compromises cell membrane integrity by inhibiting arginine biosynthesis and pyrimidine metabolism pathways, thereby increasing membrane permeability and inducing bacterial death. In an in vivo mouse model of skin wound healing, PNP-02 exhibited antibacterial efficacy similar to vancomycin. The compound demonstrated low toxicity to cultured human cells and in hemolysis assays and remained stable during serum incubation. These findings suggest that PNP-02 possesses promising bioactivity against MRSA and represents a potential novel antibacterial agent.

ObjectiveTo investigate the safety and feasibility of intra-biliary drainage tube placement after laparoscopic common bile duct exploration in elderly patients with choledocholithiasis， and to provide more options for surgical procedures in the clinical management of elderly patients with choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 52 elderly patients with choledocholithiasis who were admitted to Department of Hepatobiliary Surgery， Affiliated Dalian Friendship Hospital of Dalian Medical University， from November 2021 to October 2024. According to the biliary drainage method after surgery， the patients were divided into internal drainage group with 24 patients and T-tube drainage group with 28 patients， and there were 19 patients in each group after propensity score matching. The two groups were compared in terms of perioperative parameters and postoperative complications. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the T-tube drainage group， the internal drainage group had a significantly shorter length of postoperative hospital stay and a significantly lower volume of postoperative bile loss （Z=-2.845 and -5.633， both P<0.05）， while there were no significant differences between the two groups in time of operation， intraoperative blood loss， and drainage tube indwelling time （all P>0.05）. There were no significant differences between the two groups in postoperative bile leak， stone recurrence， biliary stricture， and drainage tube-related complications， and the internal drainage group had a significantly lower total complication rate than the T-tube drainage group ［1 （5.3%） vs 7 （36.8%）， P<0.05］. ConclusionFor elderly patients with choledocholithiasis， intra-biliary drainage tube placement after laparoscopic common bile duct exploration can shorten the length of postoperative hospital stay， reduce bile loss， and lower the incidence rate of postoperative complications， thereby helping to accelerate postoperative recovery.

Objective: To explore the learning curve of transurethral 450 nm blue light vaporization of the prostate (TUBVP) in a district hospital，in order to provide reference for clinicians who plan to perform TUBVP. Methods: The clinical data of 56 patients with benign prostatic hyperplasia (BPH) who received TUBVP performed by the same group of surgeons in Chang'an District Hospital during Jun. and Dec. 2023 were retrospectively analyzed. Cumulative sum (CUSUM) was used to fit the learning curve of ratio of volume to operating time (RVOT) of prostate volume /450 nm blue light. The learning curve was divided into different stages according to the inflection points，and the clinical data of patients operated at different stages were analyzed and compared. Results: The learning curve of TUBVP was 21 cases，including 1-21 cases in the learning stage，22-38 cases in the improvement stage and 39-56 cases in the maturity stage. With the increase of cases，the postoperative bladder irrigation time reduced \[40.00 (26.00，44.50) h vs. 23.00(20.50，34.00) h vs. 23.50(14.75，40.75) h\]，with statistical difference (P<0.05). The surgical efficiency increased \[(0.51±0.14) vs. (0.55±0.17) vs. (0.63±0.23)\]，while the reduction of hemoglobin \[(6.43±7.35) g/L vs. (5.65±10.91) g/L vs. (2.61±7.36) g/L\]，catheter indwelling time \[70.0 (66.0，106.0) h vs. 71.0 (66.0，89.0) h vs. 66.0 (58.5，78.5) h\]，and incidence of complications (9.5% vs. 5.9% vs. 0) in the three stages showed a gradually decreasing trend，but with no statistical significance (P>0.05). Conclusion: The learning curve of TUBVP is 21 cases. For clinicians in district hospitals，TUBVP is a worthy choice.
